Property 'provider.user.className' as specified in openfire.xml differs from what is stored in the database

I am configuring openfire.xml for custom database integration and following is my openfire.xml

    <?xml version="1.0" encoding="UTF-8"?>

    <!--

        This file stores bootstrap properties needed by Openfire.

        Property names must be in the format: "prop.name.is.blah=value"

        That will be stored as:

            <prop>

                <name>

                    <is>

                        <blah>value</blah>

                    </is>

                </name>

            </prop>

        Most properties are stored in the Openfire database. A

        property viewer and editor is included in the admin console.

    -->

    <!-- root element, all properties must be under this element -->

    <jive>

      <adminConsole>

        <!-- Disable either port by setting the value to -1 --> 

        <port>9090</port> 

        <securePort>9091</securePort>

      </adminConsole> 

      <locale>en</locale> 

      <!-- Network settings. By default, Openfire will bind to all network interfaces.

          Alternatively, you can specify a specific network interfaces that the server

          will listen on. For example, 127.0.0.1. This setting is generally only useful

           on multi-homed servers. -->

there are no errors in **errors.log** but I see this line in **warn.log** file

    2014.04.09 09:24:18 org.jivesoftware.util.JiveGlobals - Property 'provider.user.className' as specified in openfire.xml differs from what is stored in the database.  Please make property changes in the database instead of openfire.xml.

I am modifying the openfire.xml by looking [this][1] but still a warning.Can any body please tell me what mistake I am doing?
